Construction method for 45-DEG-inclined long-overhanging reinforced concrete structure project

Abstract

The invention relates to a construction method for a 45-DEG-inclined long-overhanging reinforced concrete structure project. When the project is constructed, a cable-stayed steel tube tower is combined with a scaffold; for a steel-structure support tower, hanging bars are adopted to resist an overturning force; for an upper-part scaffold, inclined braces are adopted to resist an overturning force; for a steel-structure support tower or an inclined-hauled steel truss with a grounded lower part, the upper part of the steel-structure support tower or the upper part of the inclined-hauled steel truss is assisted by a high support formwork with local full fastener steel tubes. The weak links or the dangerous links in a construction process are sufficiently acknowledged, the stress mechanism in the construction process of the 45-DEG-inclined long-overhanging reinforced concrete structure project is disclosed, and the requirements of economy and rationality and safety and reliability are satisfied through technical analysis, so that the construction method for the 45-DEG-inclined long-overhanging reinforced concrete structure project has the advantages of high technological content, stable structure, safety and reliability, explicit force transmission, rational stress, convenience and fastness for construction, shortened construction period for implementation, capability of prefabricating parts in factories and splicing and assembling in field, low cost and good economical efficiency.

Description

technical field [0001] The invention relates to the building construction technology of the international patent classification patent classification E04G, especially a construction method specially used for a 45° inclined large cantilever reinforced concrete structure engineering of a building. Background technique [0002] In the known technology, reinforced concrete cantilevered components, such as cantilevered beams, cantilevered slabs, cantilevered cornices, etc., are widely used in construction projects, and the design and construction of reinforced concrete cantilevered components are prone to safety problems, and quality accidents also occur. There are many, and there are many such quality accidents in the project. Such as cracks, inclination, excessive deflection affect normal use and so on. The existing construction technology is less disclosed. [0003] Patent Application No. 02154109 The construction method of Y-shaped columns and cantilevered large inclined be...

AI Technical Summary

Problems solved by technology

[0004] The stability and anti-overturning calculation of the ordinary steel pipe truss support system cannot meet and guarantee the construction quality and safety of the structure; in addition, the artificial straight thread connection operation is difficult

[0005] Especially at present, the construction method of 45° inclined large cantilever reinforced concrete structure engineering has not yet been made public.
